Abstract
BACKGROUND Cholangiohydatidosis (CH) is an evolutionary complication of hepatic cystic echinococcosis, associated with increased morbidity and mortality. The aim of this study was to describe the available evidence regarding clinical characteristics of CH, postoperative complications and hospital mortality. METHODOLOGY/PRINCIPAL FINDINGS Systematic review. Studies related to CH with no language or publication restriction were included. Sensitive searches were performed in Trip Database, SciELO, BIREME-BVS, WoS, PubMed, EMBASE and SCOPUS. MeSH and free terms were used, including articles up to April 2023. The main outcome variables were postoperative complications and hospital mortality; the secondary ones were publication year, origin and design of primary studies, main clinical manifestation, anatomical location and type of cysts, hospital stay, surgical procedure performed, reinterventions; and methodological quality of primary studies, which was assessed using MInCir-T and MInCir-P scales. Descriptive statistics, calculation of weighted averages and their comparison by least squares logistic regression were applied. 446 studies were retrieved from the searches performed, 102 of which met the inclusion and exclusion criteria. The studies analyzed represent 1241 patients. The highest proportion of articles was published in the last decade (39.2%). Reports are mainly from Turkey (28.4%), Greece (9.8%), Morocco and Spain (8.8% each). With a weighted mean of 14.3 days of hospital stance; it was verified that 26.2% of patients developed postoperative complications (74,3% Clavien y Dindo III y IV), 6.7% needed re-interventions, and 3.7% died. When comparing the variables age, postoperative complications, hospital mortality, and reinterventions in two periods of time (1982-2006 vs. 2007-2023), no statistically significant differences were found. When applying the MInCir-T and MInCir-P scales, the methodological quality of the primary studies was 9.6±1.1 and 14.5±4.3 points, respectively. CONCLUSION/SIGNIFICANCE CH is associated with severe postoperative complications and significant hospital mortality, independent of the development of therapeutic support associated with the passage of time.

Abstract
Infected hepatic echinococcosis (IHE), defined as a cystic infection, and the development of a liver abscess may be a complication in the natural history of hepatic echinococcosis. The aim of this study was to review the evidence available related to clinical, therapeutic, and prognostic aspects of IHE. We conducted a systematic review. Trip Database, BIREME-BVS, SciELO, LILACS, IBECS, PAHO-WHO; WoS, EMBASE, SCOPUS and PubMed were consulted. Studies related to IHE in humans, without language restriction, published between 1966 and 2020 were considered. Variables studied were publication year, geographical origin of the samples, number of patients, therapeutic and prognosis aspects, and methodological quality (MQ) for each article. Descriptive statistics was applied. Subsequently, weighted averages (WA) of the MQ of each article were calculated for each variable of interest. 960 related articles were identified; 47 fulfilled selection criteria, including 486 patients with a median age of 48 years, 51.6% being male. The largest proportion of articles were from Spain, India, and Greece (36.1%). Mean cyst diameter was 14.1 cm, and main location was right liver lobe (74.0%). WA for morbidity, mortality, hospital stay, and follow-up were 28.5%, 7.4%, 8.5 days and 14.8 months, respectively. The most common causative microorganisms of superinfection isolated were Enterobacteriaceae. An association with cholangitis was reported in 13.4% of cases. Mean MQ of the 47 articles included was 7.6 points. We can conclude that the information related to IHE is scarce and scattered throughout articles of small casuistry and poor quality, and consequently does not provide strong evidence.

Abstract
Objectives: Chronic pancreatitis produces disabling pain and loss of pancreatic endocrine/exocrine function. Almost half of the patients will need surgery during the course of the disease. Certain conditions, such as extrahepatic portal hypertension or cavernous transformation of the portal vein, can increase the risk of morbidity and mortality. These complications must be borne in mind in the design of the surgical treatment of chronic pancreatitis. This study is a systematic review on the coexistence of chronic pancreatitis and extrahepatic portal hypertension/cavernous transformation in patients undergoing pancreatic surgery. Methods: We conducted an unlimited search updated on 10 December 2017, which yielded 535 results. We selected 11 articles. Results: Main indication for surgery was intractable pain. Presence of extrahepatic portal hypertension and/or cavernous transformation increased intraoperative bleeding and general postoperative morbidity, though the increase in general morbidity was less when the different postoperative complications were analyzed individually. Case series showed a higher mortality in patients with extrahepatic portal hypertension. Conclusion: Little is known about the presence of extrahepatic portal hypertension in patients undergoing pancreatic surgery for chronic pancreatitis. More studies are needed in order to standardize criteria for vascular involvement in patients with chronic pancreatitis, in order to select the surgical technique and, if necessary, to establish contraindications, in this subgroup of patients.

Abstract
BACKGROUND A minor subset of primary gastrointestinal stromal tumors (GIST) can also arise outside the gastrointestinal tract, which is known as an extra-GIST (E-GIST). Primary GIST of the liver is an exceptional location.
AIM To characterize epidemiological, clinical and pathological features and options of treatments.
METHODS We performed a systematic review to search for articles on primary hepatic GIST.
RESULTS This review shows that right hepatic lobe was the most frequent location. Regarding pathological and immunohistochemical features, mitotic count was ≥ 5/50 High Power Fields in more than 50%; and CD117 was negative in only 1 patient. More than 70% of patients had a lesion with high risk of malignancy.
CONCLUSION The diagnosis of E-GIST must be considered in a liver mass. Rendering an accurate diagnosis is a challenge, as well as the confirmation of their primary or metastatic nature.

Effect of hyaluronic acid on the regulation of inflammatory mediators in osteoarthritis of the temporomandibular joint: a systematic review. Int J Oral Maxillofac Surg 2017; 46:590-595.

Abstract
Osteoarthritis is one of the most frequent pathologies affecting the temporomandibular joint (TMJ). There is evidence that the use of intra-articular hyaluronic acid (HA) for the treatment of this disorder achieves positive effects through a reduction in inflammatory mediators. A systematic review of the available evidence regarding the regulation of inflammatory mediators when applying HA in osteoarthritis of the TMJ in humans was performed. The Web of Science, Embase, ScienceDirect, MEDLINE, Scopus, EBSCOhost, and LILACS databases, SciELO library, and search engine Trip Database were searched systematically. Two thousand eight hundred and sixty-three related articles were found, of which only two met the selection criteria (both were clinical trials and evidence level 2b for treatment studies). These two articles represented a population of 87 patients. Both articles reported that the application of HA had a positive effect on the regulation of inflammatory mediators; the mediators studied were those of the plasminogen activator system and levels of nitric oxide. The limited evidence available suggests that the application of HA regulates various inflammatory mediators in osteoarthritic processes in the TMJ. Nevertheless, further evidence in this regard is required, through the study of specific pathologies of the TMJ, complementing the assessment of clinical parameters with molecular studies, and generating good quality clinical studies with larger sample sizes.

Abstract
AIM To evaluate all the references about primary gallbladder hidatidosis looking for best treatment evidence.
METHODS Search: 1966-2015 in MEDLINE, Cochrane Library, SciELO, and Tripdatabase. Key words: “gallabladder hydatid disease” and “gallbladder hydatid cyst”. We found 124 papers in our searches but only 14 papers including 16 cases were about hydatid cyst of the gallbladder (GBHC).
RESULTS Eight cases of GBHC were women and seven men. One not mentioned. Median age was 48.3 years. The most frequent clinical symptom was abdominal pain (94%) usually in the right upper quadrant. Ultrasound was performed in ten patients (62.5%) but in most cases a combination of several techniques was performed. The location of the cysts was intravesicular in five patients. Five patients presented GBHC and liver hydatid cysts. Two patients presented cholelithiasis and one choledocholithiasis. The most frequent surgical technique was cholecystectomy by laparotomy (81.25%). Simultaneous surgery of liver cysts was carried out in five cases. Eleven patients did not present postoperative complications, but one died. The mean hospital stay was seven days. No recurrence of GBHC was recorded.
CONCLUSION In GBHC, the most frequent symptom is right hypocondrium pain (evidence level V). Best diagnostic methods are ultrasound and computed tomography (level V, grade D). Suggested treatment is open cholecystectomy and postoperative albendazole (level V, grade D) obtaining good clinical results and none relapses.

Abstract
The clinical paradigm of evidence-based medicine requires a foundation of good quality research upon which clinical and epidemiological decisions can be based. Several instruments have been designed to assess research quality and validated, though most have limitations. The MINCIR scale was designed to determine the methodological quality (MQ) of clinical research, its psychometric properties for dental research involving large-scale evaluations have not yet been determined. The aim of this study was to determine the validity and reliability of the MINCIR scale for assessment of the MQ of dental therapy studies published in journals indexed in Institute for Scientific Information (ISI) databases. A validation study was performed on a sample of 99 articles from four representative ISI dental journals. Criterion validity was determined in relation to level of evidence (LoE) classification as described by the Oxford Center for Evidence-Based Medicine (OCEBM) ranking system, reliability was determined by calculation of intra-class correlation coefficient (ICC) values, and internal consistency was determined by calculation of Cronbach's alpha. Very good inter-observer reliability (ICC=0.93), excellent temporal stability (ICC=0.97), good internal consistency (Cronbach's alpha=0.77), and a strong (inverse) correlation with OCEBM LoEs (-0.807; p<.0001) were obtained. These results indicate that the MINCIR scale has adequate psychometric properties and therefore is a valid option for use in the assessment of MQ in dental therapy research articles.

Abstract
INTRODUCTION Prostate cancer (PC) treatment in early stages is radical prostatectomy (RP) or external radiotherapy (ER). There is some uncertainty regarding the development of new ER induced malignant tumors or second primary tumor (SPT), a fact influencing the choice of therapy. The purpose of this study is to determine the best therapeutic alternative for localized PC, in regards to incidence and time of development of. MATERIAL AND METHODS A systematic review of the literature is proposed by means of evaluation of studies conducted with localized PC and treated with RP or ER, published between 1990 and 2010. The Mega searchers used were Cochrane Library and Trip Database, and the data bases used were MEDLINE, OVID, Science Direct, SciELO and LiLACS, using MeSH terms and free words. The studies selected were analyzed using the MINCIR score of methodological quality (MQ) to compare articles with different design. The variables were considered to be number of patients treated, localization of lesions, global incidence of STP and MQ of the studies. Averages, medians and weighted averages (WA) were calculated. The study groups were compared using the 95% confidence intervals of the medians. RESULTS Eleven articles fulfilled the screening criteria (retrospective cohorts and case series); providing 13 series for the study. The average of MQ was 14.7 points (13 and 16 points). The most frequent localizations of STP were bladder, rectum and long. The WA of the global incidence of STP for the series was 3.6% (4.1% for ER and 2.2% RP) CONCLUSION: The information existing did not make it possible to demonstrated an association between the appearance of STP and therapies for localized PC, it even though there was a superior tendency in irradiated patients.

Abstract
A systematic review (SR) is an article on the «synthesis of the available evidence», in which a review is performed on the quantitative and qualitative aspects of primary studies, with the aim of summarising the existing information on a particular topic. After collecting the articles of interest the researchers then analyse them and compare the evidence they provide with that from similar ones. The reasons for justifying performing an SR are: when there is uncertainty as regards the effect of an intervention due to there being existing evidence against its real usefulness; when it is desired to know the magnitude of the effect of an intervention; and, when it is desired to analyse the behaviour of an intervention in subject sub-groups. The aim of this article is to perform an update on the basic concepts, indications, strengths and weaknesses of SRs, as well as the development of an SR, the most important potential biases to be taken into account in this type of design, and the basic concepts as regards the meta-analysis. Two examples of SR are also included, of use for surgeons, who often come across this type of design when searching for scientific evidence in biomedical journal bases.
